Neonatal lupus is a rare disease, with a prevalence of 1:17,000-20,000 child births. The disease is attributed to autoantibodies such as anti-Ro and anti-La. These antibodies are a common finding in Systemic Lupus Erythematosus and Sjogren disease patients. The clinical manifestations include dermatological, hematological, hepatic, neurological and cardiac involvement. Cardiac disease may be presented as atrioventricular conduction block, cardiomyopathy or endocardial fibroelastosis. If the fetus's heart is affected, the death rates may be as high as thirty percent, and dilated cardiomyopathy may evolve. About 60% of infants will require a permanent pacemaker. Routine screening and early detection are crucial for the initiation of effective treatment. Nevertheless, preventive treatment for all mothers is not recommended due to the low prevalence of the disorder and the common side effects. This article reviews the current knowledge on pathophysiology, and treatment options in neonatal lupus erythematosus.

Venous thromboembolism (VTE) is a rare disease that is being increasingly diagnosed and recognized in paediatrics in the past decade, usually as a secondary complication of primary severe underlying diseases. Apart from acquired thrombophilic risk factors, such as lupus anticoagulants, inherited thrombophilias (IT) have been established as risk factors for venous thromboembolic events in adults. In children with idiopathic VTE and in paediatric populations in which thromboses were associated with underlying medical diseases, IT have been described as additional prothrombotic risk factors. Follow-up data for VTE recurrence in children are available and suggest a recurrence rate of approximately 3% in neonates and 8% in other children. Here we present a review of the impact of IT on early onset of VTE and recurrence in children. Statistically significant associations between the IT traits investigated, e.g. factor V G1691A, factor II G20210A, protein C-, protein S-, antithrombin deficiency, elevated lipoprotein (a), combined IT and VTE onset were reported. In addition, statistically significant associations with recurrent VTE were calculated for protein S-, antithrombin-deficiency, and the factor II variant and combined IT. The absolute risk increase for VTE recurrence associated with IT ranged from 9.8 % for children carrying the factorII variant to 26% and 29% in children with combined IT and protein S-deficiency, respectively. Data obtained gave evidence that the detection of IT is clinically meaningful in children with VTE and underlines the importance of a paediatric thrombophilia screening program. Based on these data treatment algorithms have to be discussed.

The presence of lupus anticoagulant is associated with an elevated risk of venous and arterial thrombosis, and recurrent miscarriages as well. For some cases, this disease can present with bleeding as a consequence of lupus anticoagulant hypoprothrombinemia (LAHPS). LAHPS is a rare disease and it is reported to be most frequent in young females with/without systemic lupus erythematosus or in healthy children who are suffering with a viral infection. In such cases, steroid therapy is usually effective in normalizing the biological abnormalities and controlling the bleeding problems. A 34-year-old previously healthy man was admitted to our department because of his prolonged coagulation times; these abnormalities were discovered before performing orthopedic surgery. The prothrombin time (PT) was 15.2 sec, and the activated partial thromboplastin time (APTT) was 37.7 sec. A 1:1 dilution of patient plasma with normal plasma nearly corrected the PT, but this failed to correct the APTT. Evaluation of the clotting factors revealed decreased levels of factors II, V, VIII, IX and XI. The presence of LA was demonstrated by the dRVVT test, and the patient was diagnosed with LAHPS. He was successfully treated with corticosteroid before performing the orthopedic surgery.

The perforation of a mitral valve aneurysm is a rare disease which induces acute mitral regurgitation and is usually induced by infective endocarditis; however, in this case report, acute heart failure was caused by a perforated mitral valve aneurysm that was speculated to be due to Libman-Sacks endocarditis with systemic lupus erythematosis and secondary anti-phospholipid syndrome. Mitral valve plasty was performed and thereafter heart failure improved.

Evans syndrome (ES) is a rare disease characterized by the simultaneous or sequential development of autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP) and/or immune neutropenia. To better describe the characteristics and outcome of ES in adults, a survey was initiated in 2005. The data from 68 patients (60% of them women) fulfilling strict inclusion criteria for ES are reported. The mean age at time of ITP and/or AIHA onset was 52 plus or minus 33 years, both cytopenias occurred simultaneously in 37 cases (54.5%). ES was considered as "primary" in 34 patients (50%) but was associated with an underlying disorder in half of the cases, including mainly systemic lupus, lymphoproliferative disorders, and common variable immunodeficiency. All patients were given corticosteroids, but 50 of them (73%) required at least one "second-line" treatment, including splenectomy(n = 19) and rituximab (n = 11). At time of analysis, after a mean follow-up of 4.8 years, only 22 patients (32%) were in remission off treatment; 16 (24%) had died. In elderly patients, the risk of cardiovascular manifestations related to AIHA seems to be higher than the ITP-related risk of severe bleeding. In conclusion, ES is a potentially life-threatening condition that may be associated with other underlying autoimmune or lymphoproliferative disorders.

Background Lupus erythematosus tumidus (LET) is a rare disease which was first described in 1909 but has not always been considered as a separate entity of cutaneous lupus erythematosus (CLE) in the international literature. Objectives To compare characteristic features of different subtypes of CLE and to analyse whether LET can be distinguished as a separate entity in the classification system of the disease. Methods The study involved 44 patients with CLE, including 24 patients with LET, 12 with discoid lupus erythematosus (DLE) and eight with subacute CLE (SCLE), from two centres in Germany. A core set questionnaire and an SPSS database were designed to enable a consistent statistical analysis. Results Location of skin lesions did not differ significantly between the CLE subtypes; however, the activity score was significantly lower in LET than in DLE (P < 0.01), and the damage score was significantly lower in LET than in SCLE (P < 0.01) and DLE (P < 0.01). Photosensitivity and antinuclear antibodies were confirmed to be different in LET compared with SCLE and DLE but without statistical significance. Moreover, histological analysis of skin biopsy specimens showed that abundant mucin deposition is significantly more present in LET compared with SCLE (P < 0.01) and DLE (P < 0.01) while prominent interface dermatitis and alteration of hair follicles were absent in LET. Conclusions Several significant differences were found between LET and other subtypes of CLE with regard to clinical, histological and laboratory parameters. These data strongly indicate that LET should be defined as a separate entity in the classification of CLE.

Gelatinous transformation of the bone marrow is a rare disease characterised by a focal marrow hypoplasia, fat atrophy and accumulation of extracellular mucopolysaccharides abundant in hyaluronic acid, which is often associated with extreme malnutrition and weight loss. There are only two reports describing its association with systemic lupus erythematosus (SLE). One described underlying diseases in 155 cases of gelatinous transformation of the bone marrow and found one case with clinical diagnosis of SLE, but no clinical details were provided. The other described three SLE patients with gelatinous transformation of the bone marrow; however, two of these were cachectic and one was diagnosed with concomitant tuberculosis. We describe one active SLE patient without other comorbidities whose pancytopaenia was histologically confirmed as gelatinous transformation. The combination of high-dose steroid, intravenous immunoglobulin and mycophenolate mofetil improved the peripheral blood cytopaenia and reversed the bone marrow abnormalities.

Systemic lupus erythematosus (SLE) is an autoimmune disease in which organs undergo damage. Hypoparathyroidism is a rare disease, which presents in two forms: hereditary and acquired. Cases of hypoparathyroidism and SLE rarely co-exist. Only six cases have been reported; five of them first presented with lupus and then hypoparathyroidism or simultaneously. We present here developing lupus disease in a woman who had idiopathic hypoparathyroidism. According to increasing data about the autoimmune origin of idiopathic hypoparathyroidism, these case reports suggest that there may be an autoimmune process linking these diseases.

Mixed connective tissue disease (MCTD) is a rare disease that includes clinical and laboratorial manifestations of systemic lupus erythematosus, scleroderma and polymyositis that is associated with high titers of anti-U1RNP antibodies. In general, muscle involvement is subclinical, usually appearing as an increase in muscle enzyme levels that tends to be a characteristic of the initial phases of the disease. Severe clinical muscle weakness is not observed in this disease. The objective of this study is to report a rare case of a patient who presented a severe onset of myositis characterized by dysphagia, an increase in myopathy and a weakening of the cervical musculature. While there was no response to the administration of an initial dose of corticosteroids, improvement was observed after increasing the dose of corticosteroids, in addition to the initiation of pulse therapy with methylprednisolone accompanied by methotrexate treatment. The authors emphasize that there is only one previously reported case regarding a child with MCTD and severe clinical myopathy on electromyography and muscle biopsy, and they report in this article one adult female patient who presented severe myositis and was refractive to corticotherapy.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare disease. The prognosis is poor in most cases with rapid progression despite administering chemotherapy. A 67-year-old man complained of skin rashes on his back and this spread to the trunk, face, arms and thighs, and he was initially diagnosed with cutaneous lupus erythematosus according to the skin biopsy. The skin rashes then became aggravated on a trial of low dose methylprednisolone for 3 months. Repeated skin biopsy revealed a diffuse infiltration of lymphoid cells with medium sized nuclei, positive for CD4 and CD56, negative for Epstein-Barr virus (EBV), indicating a diagnosis of BPDCN. Further workups confirmed stage IVA BPDCN involving the skin, multiple lymph nodes, the peripheral blood and the bone marrow. He was treated with six cycles of combination chemotherapy consisting of ifosphamide, methotrexate, etoposide, prednisolone and L-asparaginase, and he achieved a partial response. Herein we report on a rare case of BPDCN that was initially misinterpreted as cutaneous lupus erythematosus.
